We divide 456589 by 23
The aim is to understand the frequency of 23 in 456589.

Going ahead to step 1:
4 divided by 23 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 23

On to step 2:
23 can be fit into 45 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 23 from 45 and we're left with 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 23

Let's proceed to step 3:
If we divide 226 by 23, we get 9 and a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 19 after subtracting 207 from 226.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 23

Advancing to step 4:
The number 23 fits into 195 8 times, leaving a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 198.0
If we take 184 away from 195, we end up with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 23

Advancing to step 5:
When dividing 118 by 23, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 1985.0
The remainder is 3 after subtracting 115 from 118.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 23

Let's proceed to step 6:
The number 23 fits into 39 1 times, leaving a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 19851.0
If we subtract 23 from 39, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
160 divided by 23 is 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 19851.6
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 19851.69
The remainder is 13 after subtracting 207 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
The number 23 fits into 130 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 19851.695
Subtract 115 from 130 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
The number 23 fits into 150 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 19851.6956
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
The number 23 fits into 120 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 19851.69565
Subtract 115 from 120 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
23 goes into 50 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 19851.695652
If we take 46 away from 50, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
40 divided by 23 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 19851.6956521
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 14:
170 divided by 23 is 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 19851.69565217
Deduct 161 from 170 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 19851.69565217 and a remainder of 9e-09.
